RISK MANAGEMENTDEFINITION

COMPREHENSIVE SET OF ACTIONS THATREDUCES THE RISK OF A PROBLEM, A

FAILURE, AN ACCIDENT

ASME B30.9 REQUIRES THAT SLINGUSERS SHALL BE TRAINED IN THESELECTION, INSPECTION, CAUTIONS TOPERSONNEL, EFFECTS OF ENVIRONMENT,AND RIGGING PRACTICES. SLING IDENTIFICATION IS REQUIRED ON ALLTYPES OF SLINGS

ASME B30.26 REQUIRES THAT RIGGINGHARDWARE USERS SHALL BE TRAINED INTHE SELECTION, INSPECTION, CAUTIONSTO PERSONNEL, EFFECTS OF ENVIRONMENT, AND RIGGING PRACTICES.ALL RIGGING HARDWARE TO BE IDENTIFIED BY MANUFACTURER WITHNAME OR TRADEMARK OFMANUFACTURER.

2THE BASIC RIGGING PLAN

PLAN EVERY LIFT, INCLUDE THE FOLLOWING QUESTIONSWITH THE QUESTIONS YOUR EXPERIENCE PROVIDES:1. WHO IS RESPONSIBLE (COMPETENT) FOR THE RIGGING? 2. HAS COMMUNICATIONS BEEN ESTABLISHED?3. IS THE RIGGING IN ACCEPTABLE CONDITION?4. IS THE RIGGING APPROPRIATE FOR LIFTING?5. DOES THE RIGGING HAVE PROPER IDENTIFICATION?6. DOES ALL GEAR HAVE KNOWN WORKING LOAD LIMITS?7. WHAT IS THE WEIGHT OF THE LOAD?8. WHERE IS THE LOAD’S CENTER OF GRAVITY?9. WHAT IS THE SLING ANGLE?10. WILL THERE BE ANY SIDE OR ANGULAR LOADING?11. ARE THE SLINGS PADDED AGAINST SHARP CORNERS?12. ARE THE WORKING LOAD LIMITS ADEQUATE?13. IS THE LOAD RIGGED TO THE CENTER OF GRAVITY?14. IS THE HITCH APPROPRIATE FOR THE LOAD?15. IS A TAG LINE REQUIRED TO CONTROL LOAD?16. WILL PERSONNEL BE CLEAR OF SUSPENDED LOADS?17. IS THERE ANY POSSIBILITY OF FOULING?18. WILL THE LOAD LIFT LEVEL AND BE STABLE?19. ANY UNUSUAL ENVIRONMENTAL CONCERNS?20. ANY SPECIAL REQUIREMENTS?

THE RIGGING MUST BE USED WITHIN MANUFACTURER’SRECOMMENDATIONS AND INDUSTRY STANDARDS THATINCLUDE OSHA, ASME, ANSI, API AND OTHERS.

CHOKER CAPACITY

A CHOKER HITCH HAS 80% OF THE CAPACITY OF A SIN-GLE LEG SLING ONLY IF THE ANGLE OF CHOKE IS 120DEGREES OR GREATER. CHOKE ANGLES LESS THAN 120DEGREES WILL RESULT IN A SIGNIFICANTLY REDUCEDCAPACITY.

NO LOSS IN CAPACITYRESULTS IF A CRADLEGRAB HOOK IS USED.

BASKET HITCH CAPACITYA TRUE BASKET HITCH HAS TWICE THE CAPACITY OF A SINGLE LEG ONLY IF THE LEGS ARE VERTICAL. NOTE THATTHE BASKET IS FORMED BY USING A CHAIN SLING WITH TWOMASTERLINKS AT EACH END CONNECTED TO THE HOOK.

MULTIPLE LEG SLINGSTRIPLE LEG CHAIN SLINGS HAVE 50% MORECAPACITY THAN DOUBLE LEG CHAIN SLINGS (ATSAME SLING ANGLE) ONLY IF THE CENTER OFGRAVITY IS IN CENTER OF CONNECTION POINTSAND LEGS ARE ADJUSTED PROPERLY (THEYMUST HAVE AN EQUAL SHARE OF THE LOAD).QUAD (4LEG) CHAIN SLINGS OFFER IMPROVEDSTABILITY, BUT DO NOT PROVIDE INCREASEDCAPACITY.

WHEN LIFTING VERTICALLY,THE LOAD WILL BE SHARED EQUALLY IF THE CENTER OF GRAVITY IS PLACED EQUALLY BETWEEN THE PICK POINTS.

IF THE WEIGHT OF THE LOAD IS 10,000 LBS., THEN EACH SLING WILL HAVE A LOAD OF 5,000 LBS. AND EACH SHACKLE AND EYEBOLT WILL ALSO HAVE A LOAD OF 5,000 LBS.

CENTER OF GRAVITY AND SLING LOADINGWHEN THE CENTER OF GRAVITY IS NOT EQUALLY SPACED BETWEEN THE PICK POINTS, THE SLING AND FITTINGS WILL NOT CARRY AN EQUAL SHARE OF THE LOAD. THE SLING CONNECTED TO THE PICK POINT CLOSEST TO THE CENTER OF GRAVITY WILL CARRY THE GREATEST SHARE OF THE LOAD.

SLING 2 IS CLOSEST TO COG. IT WILL HAVE THE GREATEST SHAREOF THE LOAD.

SLING 2 = 10,000 X 8 / (8+2) = 8,000 LBS.SLING 1 = 10,000 X 2 / (8+2) = 2,000 LBS.

POSITIVE LOADCONTROL

REEVING THROUGH CONNECTIONS TO LOADINCREASES LOAD ON CONNECTION FITTINGS BY AS

MUCH AS TWICE.DO NOT REEVE!

WHENEVER ANY SLING IS USED, THE FOLLOWING PRACTICES SHALL BEOBSERVED.

1. SLINGS THAT ARE DAMAGED OR DEFECTIVE SHALL NOT BE USED.2. SLINGS SHALL NOT BE SHORTENED WITH KNOTS OR BOLTS OR

OTHER MAKESHIFT DEVICES.3. SLING LEGS SHALL NOT BE KINKED.4. SLINGS SHALL NOT BE LOADED IN EXCESS OF THEIR RATED

CAPACITIES.5. SLINGS USED IN A BASKET HITCH SHALL HAVE THE LOADS

BALANCED TO PREVENT SLIPPAGE.6. SLINGS SHALL BE SECURELY ATTACHED TO THEIR LOAD.7. SLINGS SHALL BE PADDED OR PROTECTED FROM THE SHARP EDGES

OF THEIR LOADS.8. SUSPENDED LOADS SHALL BE KEPT CLEAR OF ALL OBSTRUCTION.9. ALL EMPLOYEES SHALL BE KEPT CLEAR OF LOADS ABOUT TO BE

LIFTED AND OF SUSPENDED LOADS.10. HANDS OR FINGERS SHALL NOT BE PLACED BETWEEN THE SLING

AND ITS LOAD WHILE THE SLING IS BEING TIGHTENED AROUND THELOAD.

11. SHOCK LOADING IS PROHIBITED!12. A SLING SHALL NOT BE PULLED FROM UNDER A LOAD WHEN THE

LOAD IS RESTING ON THE SLING.

INSPECTION: EACH DAY BEFORE BEING USED, THE SLING AND ALL FASTENINGS AND ATTACHMENTS SHALL BE INSPECTED FOR DAMAGE ORDEFECTS BY A COMPETENT PERSON DESIGNATED BY THE EMPLOYER.ADDITIONAL INSPECTIONS SHALL BE PERFORMED DURING SLING USEWHERE SERVICE CONDITIONS WARRANT. DAMAGED OR DEFECTIVESLINGS SHALL BE IMMEDIATELY REMOVED FROM SERVICE.
